Some implications for interstellar molecules of a low electron abundance in dense clouds
Steady-state abundances of a number of interstellar molecules are calculated with various values of metal depletion and cosmic-ray ionization rate. To reproduce the low fractional ionization recently suggested for dense clouds, metals must be depleted by a factor of at least 10/sup 4/ compared with the solar metal abundance. The effect of such strong depletion on the abundances of several important molecules is briefly discussed.
